The opening of the skies to unmanned drones has led to a surge in near misses, according to new figures released by the Federal Aviation Administration in Washington.
Since June pilots have told safety administrators of 25 near misses which could have had catastrophic consequences. Incidents have been reported across the country from a Jet Blue flight arriving at LaGuardia airport earlier this month to close calls at Norfolk, Virginia and New Orleans, Louisiana.
Only last month a drone came within 25m of a passenger plane landing at London's Southend Airport.
With companies such as Amazon talking about using drones to deliver goods, the unmanned aircraft industry is set to boom. In the United States alone, the FAA believes there could be as many as 7500 commercial drones in the skies within five years.
Film studios are among a number of industries lobbying hard for permission to use the aircraft.
